(N/A) Interphase involves a series of changes that prepare a cell for division. It is the period during which the cell experiences growth and $DNA$ replication in an orderly manner. Interphase is divided into three phases:
$G_{1}$ phase
$S$ phase
$G_{2}$ phase
$G_{1}$ phase: It is the stage during which the cell grows and prepares its $DNA$ for replication. In this phase,the cell is metabolically active.
$S$ phase: It is the stage during which $DNA$ synthesis occurs. In this phase,the amount of $DNA$ (per cell) doubles,but the chromosome number remains the same.
$G_{2}$ phase: In this phase,the cell continues to grow and prepares itself for division. The proteins and $RNA$ required for mitosis are synthesised during this stage.
